Because of their unique perspective, even relatively mundane aerial photographs tend to grab a viewer's interest. But, getting a camera up in the air isn't the easiest task, especially if you don't have your own helicopter or even a remote-controlled chopper. That's where kite photography comes in.
If you watch the video above, you can see the rather complex kite photography rig used by photographer, Rob Doolard, to get his DSLR well above where he could otherwise go. The video itself is in Dutch (which I don't speak), but there's a lot of other information out there about kite photography should you get interested after watching. But, the results really do speak for themselves.
Predictably, there are even Flickr groups dedicated to the subject with some really impressive results.
